Product Description
QK-QB Submersible Sewage Aerator introducing high-tech from Finland, is a new self-developed submersible type aerator.
Submersible sewage aerator is a essential equipment in aeration basin, it utilize fine or medium bubbles diffuse to provide aeration and mixing to process water, and widely used in many places.
• Higher oxygen conversion rate
• Fast install, no need to empty aeration tank
• 100% no clogging
• High working efficiency
• Underwater working, noiseless
• Longer life service
How It Works
The pressured air supplied by blower goes though air pipe and reach to rotor, high speed rotor hit and break pressured air into tiny bubbles.These tiny bubbles and water around are shaped to wave curve by strongly mixing of rotor. The stator channel can ensure the air-water liquid evenly distributed in different shapes of aerator basin, meantime, strong mixing flow by rotor continuously mix the water ,air and activated sludge, which ensures the ideal aeration efficiency.
The negative-pressure while submersible aerator working, lead to self priming , thus it will lower the air pressure ,supplied by blower, normally this pressure just equal to water height. So it is obviously energy-saving than traditional aerator.
Application
Such as :
• Municipal sewage treatment plant
• Industrial wastewater treatment plant
• Paper mill wastewater treatment
• Petroleum industrial wastewater treatment plant
• Chemical industrial wastewater treatment plant
• etc.
Construction
Gear motor; Air inlet pipe; Air outlet channel; Pedestal; Conical impeller; Air supply system; Electric system etc.
